Rear wheel ratchet holder - velomobile tool

Mounting the rear wheel in velomobiles (alpha 7 / 9,  DF, Milan and such) can bee a PITA because the ratchets must be pushed into position… This little tool holds them in place instead. Attach a string (or a wire / spoke) to pull it out after mounting the wheel.
